摘要
在弹性半空间Boussinesq理论解基础上,推导得到了地基中的应力解,并给出了用应力表示的地基沉降计算公式。对于给定的q–s曲线,按照最小二乘法,用解析方法对Duncan-Chang模型参数进行反演分析,工程算例显示了该方法的正确性和实用性。反演得到的地基参数能很好地反映现场沉降试验结果。
Based on the Boussinesq solution of elastic semi-infinite ground, the stress solution of ground is obtained, and the calculation formula of ground settlement is expressed by the stress solution. As for some given q - s curves, the back analysis is used to analyze parameters of Duncan-Chang model based on the least square method. It is proven that the present method is accurate and practicable, and the parameters obtained by back analysis agree well with the results of settlement experiment.
